Import a slightly modified Bayou version into svn. This is based

on the last snapshot posted by Jordan Crouse. This commit is long
overdue.

Changes by me include:

 - Rename 'utils' to 'util' for consistency with our other projects.

 - Move the main code out of src/* into the top-level directory.

 - Add missing license headers to the following files:
   Makefile, pbuilder/liblar/Makefile, util/pbuilder/Makefile.

 - Dropped the util/pbuilder/lzma completely. I'm working on reusing
   the lzma/ dir from v3 via svn:externals. Alas, this also means
   that Bayou won't yet compile out of the box.

 - Coding-style and white-space fixes (indent) for all files.
